Implementation of Advanced, Intelligent Wireless Access Nodes

This paper summarizes the innovations that are considered towards the development of autonomous plug –and-play wireless access nodes. These nodes are to be utilized in all-IP environments, performing a wide range of functions such as macro-mobility management, AAA (Authentication, Authorisation, Accounting) procedures, provision of secure communications, resources management, applications logic execution, etc. It is demonstrated that the described idea focusing on intelligent access nodes removes the need for intelligent core networks. The requirements for the above mentioned intelligent network nodes are described, stating their main characteristics; automatic configuration, independence from centralised functions, capability of dynamically building the control communication interfaces. Furthermore the extension or the use of open access APIs to the wireless access node is suggested. A description of the work performed in included comprising a functional overview of the gateway system, description of the web-services interfaces for execution of applications, and implementation of mobility management. The paper concludes with a description of the establishment of trustworthy and secure management relationships together with the presentation of the management of user authorisation procedures
